RELATED APPLICATIONS

This is a continuation of application Ser. No. 13/673,662 filed Nov. 9,2012, the teachings of which are incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates generally to apparatus, systems, andmethods for aiding machine processes, and more particularly, for aidingprocesses for punching or pressing machines.

BACKGROUND

Sheet metal and other workpieces can be fabricated into a wide range ofuseful products. To that end, the fabrication (i.e., manufacturing)processes commonly involve making various bends and/or forming holes inthe sheet metal and other workpieces. The types of equipment generallyused in such processes include turret presses and other industrialpresses (such as single-station presses), Trumpf style machine tools andother rail type systems, press brakes, sheet feed systems, coil feedsystems, and other types of fabrication equipment adapted for punchingor pressing sheet materials.

Concerning press brakes, they are equipped with a lower table and anupper table, and are commonly used for deforming metal workpieces. Oneof the tables (typically the upper table) is configured to be verticallymovable toward the other table. To that end, forming tools are mountedto the tables so that when one table is brought toward the other, aworkpiece positioned there between can be bent into an appropriateshape. Typically, the upper table includes a male forming tool (a punch)having a bottom workpiece-deforming surface (such as a V-shapedsurface), and the bottom table has an appropriately-shaped female tool(a die) having an upper surface vertically aligned with theworkpiece-deforming surface of the male tool.

As is known, the forming tools used with press brakes must be carefullypositioned on the press tables in order to bend the workpiece to precisespecifications. To aid the operator in this regard, certain press brakeshave been fabricated with positioning systems. Such positioning systems,in many cases, are provided on a front side of the press brake, and spana considerable length of the tables of the press brake. The positioningsystems have been known to utilize rulers or scales (e.g., which can beilluminated from behind) or light-emitting diode (LED) mechanisms, suchan LED strip. For example, in the case of LED strips, they are typicallycontained within an enclosure mounted on the press brake, wherein suchstrip spans an extent of the enclosure and is visible through a clearsubstrate (such as glass or plastic) on a front side of the enclosure.

In some conventional processes, deforming parameters for a press brakeoperation are generally entered into a computer console that is hardwired to the press brake. For press brakes having a positioning systemas described above, the console is similarly wired thereto. As such,once a machine operation is entered into the press brake console, thepositioning system is used to illuminate corresponding segments (of theLED strip or ruler/scale) to indicate requisite mounting positions(e.g., particular locations along a length of the table) for formingtools on the press brake.

While the above-described positioning systems and other conventionaltypes have been of use for positioning forming tools on press brakes,the designs of such systems have limited their use and furtherfunctionality. The present invention addresses these and otherlimitations.

DETAILED DESCRIPTION

The following detailed description should be read with reference to thedrawings, in which like elements in different drawings are numberedidentically. The drawings depict selected embodiments and are notintended to limit the scope of the invention. It will be understood thatembodiments shown in the drawings and described below are merely forillustrative purposes, and are not intended to limit the scope of theinvention as defined in the claims.

As described above, certain punching or pressing machine types (such asdown-acting or up-acting press brakes) have been configured withpositioning systems. For example, with regard to press brakes, thepositioning systems have been used to indicate mounting positions forforming tools on the press tables; however, the designs of these systemshave availed little other information, such as quantitative data, to beconveyed to the operator. This is due in part to limitations of themechanisms used with the positioning systems, such as LED strips orrulers/scales. To that end, LED strips or rulers/scales, by their verynature (and particularly when configured to span an extent of pressbrake tables) are geared for providing measurement information. Thus,even if desired, there is little possibility of expanding thefunctionality of these positioning systems without significantlyaltering (e.g., adding to) their designs and constructions. However, thesizes of these conventional positioning systems can already beproblematic, in terms of impeding certain machining operations due toclearance issues with regard to workpieces. These are just some of theshortcomings which embodiments of the present invention are intended toaddress. To that end, embodiments described herein focus on displaydevices, for example, position, information, and interactive displaydevices (PIIDDs). While this description focuses on press brake designs,it should be understood that the embodied display devices are applicablefor use on virtually any pressing or punching machinery.

FIG. 1 shows a perspective view of a representative press brake 10 witha display device 12 mounted thereon, in accordance with certainembodiments of the invention. Conversely, FIG. 2 shows a side elevationview of a press brake 11 and the display device 12 of FIG. 1. Asdescribed above, while FIG. 1 shows a representative press brake 10, itis sufficient for effectively depicting one configuration of the displaydevice 12 and an exemplary mounting location for the device 12 on thepress brake 10. To that end (and as later described), the display device12 shown in FIG. 1 can be representative of a single segment 20 of adisplay device of the invention used on a press brake of longer extent.

With continued reference to FIG. 1, the display device 12 involves abar-like body that can be selectively located on a front face of thepress brake 10. In some cases as shown, the display device 12 can bepositioned on one of the tables (or beams) 14 of the press brake 10. Forexample, the device 12 can be positioned on an upper table 14 a, and canbe located as close to the corresponding clamping beams 16 (of the uppertable 14 a) as desired. The general size of the display device 12 (aslater described) contributes to the device's versatility with regard topositioning. In certain embodiments as shown, the display device 12 canbe positioned to abut the clamping beams 16 of the upper table 14 a.Such position is favorable not only because the display device 12 can beprovided adjacent to the clamping beams 16 and forming tools 18 to beheld thereby (shown in FIG. 2), but the device 12 can also form somewhatof a protective cover (or hood) for the beams 16. However, as will beappreciated from the description herein, placement of the display device12 is not required at such location on the press brake 10. Instead,characteristics of the display device 12 enable it to be selectivelypositioned (and in some cases, partially or wholly repositioned) asdesired. To that end, embodiments described herein include displaydevices being configured in a variety of differing forms (such as device12), enabling the devices to be widely versatile with regard to beingadapted for and positioned on pressing or punching machines.

As alluded to above, locating the display device 12 on either of thepress brake tables 14 (such as the upper table 14 a) is made possiblevia the device's characteristics, including its generally compact sizeand manageable weight. As a consequence of its size, the display device12 can be handled with relative ease and can be positioned on the pressbrake 10 without generally impeding (i.e., adversely affecting orinterfering with) its deforming operations. One characteristic of thedisplay device 12 is that it is quite shallow in depth. In certainembodiments as shown in FIG. 2, the device 12 has a depth less than thedepths of either of the press tables 14 by at least ⅛. In other andperhaps more preferable embodiments, the device 12 can have a depth lessthan the depths of either of the press tables 14 by at least ¼. Infurther and perhaps more preferable embodiments, the device 12 can havea depth less than the depths of either of the press tables 14 by atleast ½. In light of its shallow depth, the display device 12 can belocated on either of the tables 14 without significantly adding to thetable's front profile. By way of comparison, many known positioningsystems protrude considerably from the front surface of the pressbrake's upper table 14 a, thereby limiting the range of angles to whichcertain workpieces can be bent. For example, certain workpieces may needto be bent upwardly in close proximity to the upper table 14 a. Thedisplay device 12, with its shallow depth, is of limited risk to causesuch clearance problems during deforming operations of the press brake10. However, even in the unlikely scenario that bend clearance becomesan issue, configurations of the display device 12 (as described later)enable partial or wholly repositioning as desired.

FIG. 3A shows an enlarged perspective view of the display device 12 ofFIG. 1 in stand-alone (or free-standing) form in accordance with certainembodiments of the invention, while FIG. 3B shows an assembly view ofthe display device 12. Via these drawings (and the below descriptionconcerning size parameters) of the display device 12, the skilledartisan can better appreciate the device's general compactness andshallow depth. In certain embodiments as shown, the display device 12can be formed of one continuous segment (or single integral body) 20having desired length. However, the invention should not be limited tosuch, as the display device 12 can just as well be formed of one or moresegments 20. To that end, FIGS. 4, 4A and 4B show a plurality ofexemplary segments 20 that can be utilized in configuring the displaydevice 12 in accordance with certain embodiments of the invention. Forexample, as shown, the segments 20 can be formed as desired with regardto extent (e.g., having exemplary lengths, such as “x”, “y”, “z”, orother lengths) and configuration (e.g., having any quantity of displays24, such as one, two, or three or more displays).

In certain embodiments, as should be appreciated from FIG. 1, the lengthof the display device 12 can extend across (or span) the entire lengthof the press brake tables 14. To that end, as described above, thedisplay device 12 can be formed of one or more segments 20, with eachsegment 20 formed of one or more displays 24. As is known, industrialpresses (such as press brakes) are fabricated to come in a variety ofdifferent sizes. Thus, by configuring it to be formed of a plurality ofsegments 20, the display device 12 can be made modular and in turn,highly adaptable to varying lengths of press brake tables. Configuringthe display device 12 to be modular in this fashion enables variable yetquick construction of devices 12 of any desired length; i.e., by joininga requisite quantity of segments 20 together in end-to-end fashion. Thesegments 20 can each be of similar length; however, the invention shouldnot be so limited. In certain embodiments, the segments 20 areconfigured to be at least 12″ in length, and in perhaps more preferableembodiments, the segments 20 are configured to be between approximately18″ and approximately 48″ in length, and perhaps in most preferredembodiments, the segments 20 are configured to be between approximately24″ and approximately 36″ in length.

As described above, and with reference to FIG. 3A, the display device 12(or segments 20 thereof) can be configured to include one or moredisplays 24. However, as further described above with further referenceto FIGS. 4, 4A and 4B, quantities and sizes of the displays 24 can bevaried as desired. Looking back to FIG. 3B, in certain embodiments, aplurality of displays 24 can be joined in end-to-end manner to form thedisplay device 12 (or a segment 20 thereof) via use of a channel 23. Thechannel 23, in certain embodiments as shown, is defined with upper andlower inner surfaces 23 a, 23 b sized to accommodate corresponding upperand lower outer ends 24 a, 24 b of the displays 24. As such, thedisplays 24 can be inserted (or slid) one-by-one into the channel 23,with end caps 26 being employed on opposing ends of the channel 23 forretaining the displays 24 inserted therein. More will be later describedconcerning the collective functioning of these displays 24. However, atthis point, it should be appreciated that even with the use of suchchannel 23, the display device 12 is still afforded a shallow depth anda height not much greater than that of the displays 24. Thus, asdescribed above, the display device 12 can be positioned on press brakesas desired. To that end, the display device 12 can be configured for useon new machines, as well as being configured and correspondingly sizedfor use on existing machines (i.e., retrofit applications).

The displays 24 can be electrical ink (“e-ink”), LED, LCD, or other likedisplay types. In the case of e-ink type displays, their front surfacesare commonly configured to exhibit high-impact properties. Likewise, LEDand LCD type displays can configured with high-impact front surfaces.Therefore, unlike positioning systems used to date with punching orpressing machines, the display device 12 does not dictate using afurther protective enclosure therefor; although, the design of thedisplay device 12 does not prevent a protective covering from beingmounted over the device's front surface, if desired. However, as aconsequence of not dictating a protective enclosure or covering, thedisplays 24 can be integrally-formed portions of the display device 12.

Being of e-ink, LED, LCD, or other like display types, the displays 24are capable of being linked (e.g., electrically connected in end-to-endfashion) and synched, availing the connected displays 24 to functioncollectively. For example, as shown with reference to FIG. 5, thedisplays 24 are capable of exhibiting proper positions for forming tools18 to be used on the clamping beams 16, according to deformingoperations programmed for the press brake 10. To that end, whenlinked/synched, the displays 24 are configured for collectivelyexhibiting extents of the clamping beams 16 on the press tables 14(corresponding to the positions of the displays 24 on the tables 14),and proper positions for the forming tools 18 to be clamped thereto. Thedisplays 24 are further capable of exhibiting a wide variety ofadditional information (e.g., parameters relating to the programmeddeforming operations), as later described herein.

Continuing with the above, the displays 24 being of e-ink, LED, LCD, orother like display types contribute to the design versatility of thedisplay device 12. For example, as described above, the displays 24 canbe fabricated to have a length as long as desired, or as small as 2″ inlength. To that end, based on length of the display device 12 (orquantities and lengths of its segments 20, as applicable), the displays24 can be correspondingly sized to span across the display device 12 (orthe segments 20 thereof). For example, with reference to the displaydevice 12 shown in FIG. 1 (with enlarged view of such shown in FIG. 3),the device 12 can be formed as one segment 20 with a plurality oflinked/synched displays 24. As described above, configuring the displaydevice 12 to be formed of a plurality of joined segments 20 enables thedevice's length to be varied as desired. To that same end, the displays24 can be preconfigured to be of varying length(s) to correspondinglyspan the length of such segments 20 as desired.

Continuing with the above, while the displays 24 can be fabricated tohave lengths as desired, using displays 24 of a more typical andreadily-available (i.e., standard) length can be more cost effective.For example, in certain embodiments, a significant extent of the displaydevice 12 (or the segments 20 thereof) can be configured with displays24 of such standard length. In such embodiments, the displays 24 of thedisplay device 12 are configured to be at least 6″ in length, andperhaps in more preferable embodiments, the displays 24 are configuredto be between approximately 9″ and approximately 36″ in length, andperhaps in most preferred embodiments, the displays 24 are configured tobe between approximately 12″ and approximately 20″ in length. However,in some cases, areas of the display device 12 may dictate using one ormore displays 24 of non-standard (or atypical) length (such as at one ormore ends of the device 12) to correspondingly enable the device 12 toextend across the tables 14. In these cases, the e-ink, LED, LCD, orother like display types permit such atypical sizing.

With further reference to FIG. 5, the drawing illustrates a segment 20of the display device 12 (which can define the device 12 wholly, or inpart as one of a plurality of segments 20 thereof). Similar to FIG. 3A,the segment 20 of the display device 12 is shown in stand-alone (orfree-standing) form, but with detail being provided on the displays 24in accordance with certain embodiments of the invention. As describedabove, when linked/synched, the displays 24 are configured to functioncollectively in exhibiting corresponding extents of the clamping beams16 and proper positions for the forming tools 18 to be used thereon.With continued reference to the segment 20 shown in FIG. 5, it should beappreciated that the electronics and wiring for such linking/synchingbetween the displays 24 are generally concealed (and protected) withinthe displays 24 themselves. In certain embodiments, a power source (notvisibly shown), such as one or more rechargeable batteries, can befurther provided within the displays 24 to provide power as needed(e.g., for emergency power). Other features of the displays 24, e.g.,with reference to the display 24 shown in FIG. 3A, can involve one ormore of power switch 17, screen controls 19, and speakers 21 for audioinput/output.

As described above, in certain embodiments, segments 20 of the displaydevice 12 can be configured with end caps 26. As should be appreciated,in joining segments end-to-end, the end caps 26 can provide a platformfor operably joining segments 20 in end-to-end fashion. With referenceback to FIG. 3B, in certain embodiments, the end caps 26 can also beconfigured to function as an intermediary in linking/synching ofdisplays 24 held within a given segment 20 and/or linking/synching ofdisplays 24 of two or more segments 20. To that end, in certainembodiments as shown in FIG. 4, the end caps 26 can be configured with aconnector 25 for power and data transmission (e.g., USB, Ethernet, etc.)to/from the displays 24 of the segment 20. Further, in certainembodiments, and with reference to FIGS. 4 and 5, opposing ends 24 c, 24d of the displays 24 are configured with a like connector 25 for powerand data transmission (e.g., USB, Ethernet, etc.) for linking/synchingpurposes, e.g., either with the connector 25 of the end caps 26 (forcommunication with other displays 24 of adjoined segments 20 of thedisplay device 12) or other displays 24 of the same segment 20. Asshown, in certain embodiments, one or more further connectors can beprovided on one or more of the ends 24 c, 24 d of the displays 24. Forexample, as shown, one such connector 27 a can be provided on displayend 24 c for bringing power to the display 24, e.g., for chargingemergency power source thereof as applicable.

More description of the linking/synching will be described below withrespect to FIGS. 7-9. However, based on the displays 24 being configuredwith such linking/synching connectors 25, it should be appreciated thatone or more of the displays 24 can be removed and repositioned from thedisplay device 12 if its original location (relative to the rest of thedisplay device 12) impedes a particular deforming operation of the pressbrake 10. An example of such repositioning is illustrated in FIG. 6,whereby one of the displays 24 is shown as having been repositionedapart from the other displays 24 of the display device 12. As shown, therepositioned display 24 is moved to a higher height on the upper table14 a than the other displays 24, yet can still be linked/synched withthe other displays 24 via the use of electrical jumper wires 27extending between the connectors 25 of the displays 24, in accordancewith certain embodiments of the invention.

FIGS. 7A-7C show different views of an exemplary display 24′ forming adisplay device 12′ for a press brake (such as press brake 10 of FIG. 1)in accordance with certain embodiments of the invention. While similarto the displays 24 already described, the display 24′ of FIG. 7A-7C isconfigured to function with the press brake 10 in a singular capacity,conveying information pertaining to each of the deforming operationsprogrammed for the press brake 10. As such, the display 24′ is sized toextend across a corresponding extent of the press tables 14 of the pressbrake 10. FIGS. 7A-7C respectively illustrate front, side, and enlargedpartial side elevation views of the display 24′. Given the singular useof such display 24′ as the display device 12′ for the press brake 10,linking/synching connectors 25 (such as described above with referenceto the displays 24 of FIG. 3B) are not required (and thus, not defined)for the display 24′. Nevertheless, it should be appreciated that suchconnectors 25 can be provided with the display 24′ if desired.

Alternately, in certain embodiments and perhaps most clearly shown inFIG. 7C, the display 24′ can be configured with an electrical strip 29on its upper end 24 a′ for power and data communication thereto. Incertain embodiments, the electrical strip 29 extends across the lengthof the upper end 24 a′ to contact with corresponding inputs as neededfor powering and data transmission purposes. To that end, and as furthershown in FIG. 7C, the electrical strip 29 can include a plurality ofcontacts, e.g., two contacts 31 for power and one contact 33 for datatransmission. FIG. 8 shows a side elevation view of an upper press table14 a of press brake 10 in accordance with certain embodiments of theinvention. As illustrated, and with reference to FIG. 1, the upper presstable 14 a can be defined with a shelf 15 including a correspondingelectrical strip 29′ and connectors 31′, 33′ configured to align withand contact the electrical strip 29 of the display 24′ and itsconnectors 31, 33. It should be appreciated that upon powering thedisplay device 12′ in this fashion, the electrical strip 29 can beadditionally tapped in powering any further electrically-drivenaccessories that may be used (or run and controlled from the displaydevice 12′) at or near the press tables 14. Alternately, even though thedisplay 24′ may not be configured with connectors 25 (for power/datatransmission, see FIG. 3B), such connectors 25 can be provided with thedisplay 24′ as desired. To that end, in certain embodiments, the displaydevice 12′ can correspondingly serve as a bridge to bring power to anyof the same electrically-driven accessories that may be used (or run andcontrolled from the display device 12′) at or near the press tables 14.

FIGS. 9A-9C show further detail with regard to features of the displays24 of FIGS. 4A and 4B for linking/synching functionality with regard toother displays 24 of the display device 12. FIG. 9A illustrates aperspective view of a display 24 in accordance with certain embodimentsof the invention, while FIGS. 9B and 9C show perspective views ofexemplary configurations of opposing ends 24 c and 24 d of the display24. As shown (and as previously described above), each of the displayends 24 c, 24 d is configured with a connector 25 for power and datatransmission (e.g., USB, Ethernet, etc.). To that end, these connectors25 are female receptacles, wherein one of the connectors 25 of eachdisplay 24 further includes a two-way male plug 25 a for bridging theconnectors 25 of two of the displays 24 for linking/synching purposes.As described above with reference to FIG. 3B, in certain embodiments,one or more further connectors can be provided on the display ends 24 c,24 d. For example, as previously described above, one such furtherconnector 27 a can be provided on display end 24 c for bringing power tothe display 24. Alternatively or in combination, another furtherconnector 27 b can be provided to accept a data card 35 therein.

Turning back to the functionality of the display device 12, as aconsequence of its displays 24 being of e-ink, LED, LCD, or other likedisplay types, information conveyed by the displays 24 can be virtuallywithout limit, both in terms of quantitative and/or qualitativeinformation. To that end, each display 24 is capable of providing detailand characteristics which would be difficult if not impossible toprovide with the types of positioning systems constructed to date withpunching or pressing machinery. As described above and as shown in FIG.5, the displays 24, in certain embodiments, convey information involvingthe forming tools 18 and the clamping beams 16 of the press brake tables14. For example, the displays 24 can be configured to showrepresentations 18 a′ and 18 b′ corresponding to the to-be-used punches18 a and dies 18 b, respectively, and their proper positions withrespect to corresponding extents of the clamping beams 16. Furtherdetail concerning this will be described below; however, at this point,it should be appreciated that such representations are but one way bywhich characteristics of the requisite forming tools 18 can be conveyed,and in turn clearly identified by the operator. Likewise, and withreference back to FIG. 1, the displays 24 can also be configured toexhibit representations 16 a′ and 16 b′ for the upper clamping beam 16 aand lower clamping beam 16 b, respectively.

Each display 24, in certain embodiments, can be thought of as includinga plurality of partitions, with each partition configured to convey oneor more forms of information to the operator. For example, as shown inFIG. 5, each display 24 includes an upper partition 24 e configured toexhibit a corresponding representative section of the upper clampingbeam 16 a (via representation 16 a′) and the punches 18 a (viarepresentation 18 a′) to be clamped thereon for a programmed deformingoperation. Likewise, each display 24 includes a lower partition 24 fconfigured to exhibit a corresponding representative section of thelower clamping beam 16 b (via representation 16 b′) and the dies 18 b(via representation 18 b′) to be clamped thereon. In certain embodimentsas further shown, located between the upper and lower partitions 24 a,24 b of each display 24 is an axis 28 showing corresponding lengthdimension of the section of the clamping beams 14 correspondinglyassociated with the display 24. Given the above, it should beappreciated that the displays 24 are configured to depict the formingtools 18 as they should be properly positioned on the press brakeclamping beams 16. However, the displays 24 also offer degrees of detailthat not only enhance the tooling/tables relationship, but also providea format of providing additional information to be conveyed by thedisplay device 12 and additional functionality therefor, as describedbelow.

In certain embodiments, such additional information can relate tocharacteristics pertaining to one or more of the press brake 10, thedisplay device 12, the press brake tables 14 (or the clamping beams 16thereof), and the forming tools 18 to be used. For example, suchinformation relating to the tools 18 can include corresponding partnumbers 30 (as shown in FIG. 5), part dimensions, part manufacturer,etc. In certain embodiments, as shown in FIG. 5, the additionalinformation pertaining to the tools 18 can be correspondinglysuperimposed on the tool representations 18 a′, 18 b′. Likewise,information pertaining to the status of the clamping beams 16 can becorrespondingly superimposed on the clamping beam representations 16 a′,16 b′, examples of which will be described later. As further shown inFIG. 6, the displays 24 have portions external to (or outside) theforming tool and clamping beam representations, i.e., empty space areas32. In certain embodiments, these empty space areas 32 involve portionsof the displays 24 configured to be interfaced by the operator so as toretrieve details regarding the operations programmed for the press brake10 and control characteristics for the display device 12. More of thiswill be described below. However, at this point, it should be understoodthat such details can be retrieved (in multiple languages) forinformational and/or modifying purposes, and that these details involveany of a plurality of aspects, such as pressing angle, back gagesettings, crowning parameters, assessing part drawings to verifydimensions, linking to web sites for additional information, contactingthe machine or tooling manufacturer for customer service, bendingsequence and/or change of tools 18 needed therefor, and parameters ofthe console 36 (shown in FIG. 12) used with the press brake 10.

To this point, the display device 12 has been described as a bar-likebody that is selectively located on a press brake 10, and with furtherreference back to FIG. 1, in certain embodiments, the device 12 can bepositioned on an upper table 14 a of the press brake 10, and located asclose to the upper clamping beam 16 a as desired. To that end,embodiments have been described (with reference to FIG. 2) in which thedisplay device 12 is configured to sit atop the upper table 14 a,thereby adding to the front profile of the table 14 a, even if slightlydue to the shallow depth of the display device 12. To that end, while itis reduced, there is the possibility that the display device 12 maystill impede with certain deforming operations of the press brake 10.One way of addressing this issue is configuring the display device 12 tobe separated and repositioned in part, as exemplified with reference toFIG. 6. However, another way of addressing this issue is to prevent thefront profile of the press brake 10 from being increased with the use ofthe display device 12. FIGS. 10A-10C illustrate correspondingconfigurations for the display device and the press brake for achievingthis, as described below.

FIG. 10A shows a perspective view of a representative press brake 10′with a display device 12 mounted thereon, in accordance with certainembodiments of the invention, while FIG. 10B and FIG. 10C show an uppertable 14 a′ of the press brake 10′ with the display device 12 mountedthereon, and show the upper table 14 a′ and device 12 separated,respectively. With reference to FIG. 10C, the upper table 14 a′ isprovided with a depression 35 sized to accommodate the display device 12in recessed orientation in relation to the front surface 37 of the uppertable 14 a′. In certain embodiments as shown with reference to FIG. 10B,the depression 35 can be defined to accommodate the display device 12 oneach of its sides in a flush manner; however, the invention should notbe limited to such. Instead, in other perhaps more preferableembodiments, the depression 35 can be defined to be significantly largerthan a size of the display device 12 in order to accommodatelarger-sizes of the display devices 12, if needed. Further, while thedisplay device 12 is shown as a single display 24 (e.g., as previouslyexemplified in FIG. 5), the invention should not be limited to such. Forexample, the display device 12 can just as well involve theconfiguration of FIG. 1 (e.g., having channel 23 and plurality ofdisplays 24); however, it should be appreciated that the depression 35would in turn need to be extended in size (e.g., expanded and deepened)so as to accommodate in flush manner the display device 12 when usedwith the channel 23 and end caps 26.

Continuing with the above, the display devices 12, 12′ described to thispoint are adaptable for conveying a wealth both of quantitative andqualitative information concerning programmed deforming operations. As aconsequence, the displays 24 of such devices 12, 12′ dictate a suitablescreen size to exhibit such information. However, if this informationwas to be refined to only a subset of such information, such as onlyinvolving forming tool mounting position information, the screen sizecould be significantly decreased in size, e.g., in height. Consequently,the press brake area accommodated by such display device 12″ (asexemplified in FIGS. 11A and 11B) would be correspondingly reduced. Inparticular, in certain embodiments, the height of the display device12″, in using one or more displays 24″ of e-ink, LED, LCD, or other likedisplay types, could be decreased in size such that its exhibitedposition information can be provided atop the press brake tables 14, yetcloser in proximity to corresponding clamping beams 16 (as opposed todisplay devices 12, 12′). In certain embodiments, the height of thedisplay device 12″ is less than ½ the height of the display device 12 ofFIG. 1 and the display device 12′ of FIG. 8. To that end, FIG. 11A showsa perspective view of the representative press brake 10 of FIG. 1 withdisplay device 12″ mounted on the upper press table 14 a, in accordancewith certain embodiments of the invention. Furthermore, in limiting thescope of information to forming tool mounting position information, theheight of the display device 12″ can be decreased to such extent thatthe device 12″ can be located on either of the clamping beams 16. Tothat end, FIG. 11B illustrates a perspective view of the representativepress brake 10 of FIG. 1 with display device 12″ mounted on the upperclamping beam 16 a, in accordance with certain embodiments of theinvention. Alternatively, and with reference to FIGS. 10A-10C, incertain embodiments, the display device 12″ can be similarly recessed ina depression of one or more of the clamping beams 16.

With reference back to FIG. 1, in certain embodiments, a display tablet22 is provided on the front surface of the press brake upper table 14 a.The display tablet 22 is a computing unit, and in certain embodiments,can involve any one of the well-known commercially-available computingtablets. Examples of such tablets include Apple IPad, Samsung Galaxy,Acer Iconia, Amazon Kindle, Google Nexus, etc. As should be appreciated,the display tablet 22 has certain characteristics similar to those ofthe display device 12. For example, the display tablet 22 is quitecompact in size, e.g., possibly having depth to be even less than thatof the display device 12. With reference to FIG. 2, in certainembodiments, the tablet 22 has a depth less than ½ the depth of thedisplay device 12. Further, with reference to FIG. 1, the tablet 22includes a screen which, in certain embodiments, is of greater size thanthat of any of the displays 24 of the display device 12.

Given the above-noted characteristics, the display tablet 22 can be usedand positioned on the press brake 10 as desired. For example, as shownin FIG. 1, the display tablet 22 may be centrally positioned on theupper beam 14 a of the press brake, atop the display device 12. To thatend, the display tablet 22 can be used in conjunction with the displaydevice 12. For example, in certain embodiments, the display tablet 22can be used to selectively show parameters of any of the displays 24 ofthe display device 12. Such parameters can include any of theaforementioned details regarding operations programmed for the pressbrake 10 and control characteristics for the display device 12. As aconsequence, the displays 24 of the display device 12 can be regulatedto showing characteristics pertaining to the clamping beams 16 and theforming tools 18 to be clamped thereon. However, the invention shouldnot be limited to such. For example, the display tablet 22 can be usedto show parameters of any of the press brake 10, the display device 12,the press tables 14 (and clamping beams thereof 16), and the formingtools 18. In one such application, as exemplified in FIG. 19, the tablet22 can be used to show tool parameters (e.g., profiles) which could beshown in larger (and thus, more enhanced) detail as opposed to thedisplays 24 of the display device 12. One particularly advantageousfeature of the display tablet 22 is its portability, such that theoperator can work at any location around the press brake 10 whilecarrying and working from the tablet 22. More will be described of thislater.

To this point, the information described as being exhibited (andconveyed to the operator) by the embodied display device 12 can beconsidered as static, meaning that the information is provided to thedevice 12 to be subsequently shown thereon (in some cases, as needed).As the skilled artisan would appreciate, a console (e.g., a PC or otherlike computer system) is typically used by a press brake operator forcontrolling the press brake 10 and selecting bending operationstherefor. In general, the console is hard wired to, yet positionedremote from the deforming area of, the press brake 10. FIG. 12 showssuch an exemplary press brake work area 34 in accordance with certainembodiments of the invention, showing the representative press brake 10of FIG. 1 and exemplary console 36. The display device 12, in certainembodiments, can be configured to function as a “supplemental” device,which, as described above, provides static information to the operatorrelating to the press brake operations selected via the console 36. Insuch case, the console 36 is configured to pass along information bothto the display device 12 and to the press brake 10. As should beappreciated, the display tablet 22 can be configured to receiveinformation from one or more of the display device 12 and the console36.

Communication from the console 36 to the display device 12 can be theresult of the console 36 being hard wired to the bar 12. However, incertain embodiments, the display device 12 is configured for receivingcommunications from the console 36 in a wireless manner 38. As describedabove, the display tablet 22 is similarly configured for such wirelesscommunication 38 with the display device 12. Wireless designs are wellknown in the art. For example, the display device 12 can be equippedwith one or more conventional receivers or transceivers andcorresponding electronics to function with Wi-Fi, Bluetooth, or otherwireless protocols. As should be understood, and with reference to FIG.5, electrical signals wirelessly received by the display device 12 wouldbe processed (e.g., internal to the device 12) and the informationcommunicated therein would be respectively routed to the displays 24 ofthe device 12 as a result of the displays 24 being synched, as describedabove. Further underlying conditions in configuring the display device12 to be able to communicate with the console 36 involve the controlsystem of the device 12 being properly configured to link with thecontrol system of the console 36. This linking generally involves theoperating systems and processing protocols of the device 12 and console36 to be aligned. In new machine design applications, this linking caninvolve an easier process due to configuration parameters of the controlsystems being known from the start. However, for existing machine designapplications, the console's control system needs to be determined inadvance so the display device control system can be designed andprogrammed accordingly.

As alluded to above, the display device 12 can be configured to providea plurality of information regarding operations programmed for the pressbrake 10 and control characteristics for the device 12. However, asshould be appreciated (particularly in view of the exemplary segment 20shown in FIG. 5), the information exhibited on the displays 24 (e.g.,the clamping beam representations 16 a′, 16 b′ and tool representation18 a′, 18 b′) already utilizes a majority of the screen space. Thus, incertain embodiments, the display device 12 can also be configured tofunction as an “interfacing” device. As described above, informationregarding operations programmed for the press brake 10 and controlcharacteristics for the display device 12 can be accessed (and furtheror alternatively exhibited by the displays 24) as desired. In certainembodiments, such information is retrieved via the user interfacing withthe displays 24. To that end, such information can be shifted as desiredby the operator from the displays 24 to the display tablet 22.

E-ink, LED, LCD, or other like display types can be configured for touchscreen functionality. As should be appreciated, such functionality isgenerally processor driven. To that end, in certain embodiments, eachdisplay 24 can be configured to generate varied resistive or capacitiveresponse for a particular set of distinct finger contacts (e.g.,distinguished by quantity of fingers and/or grouping of fingers)applying instantaneous pressure (e.g., via a tap of the fingers) on thedisplay screen. Each particular resistive or capacitive response (whenrun through an internal processor) results in distinct informationregarding the programmed press brake operations or controlcharacteristics for the display device 10 being retrieved (from internalmemory storage) and exhibited on the display 24. For example, asillustrated in FIG. 18B, a tap or swipe on a particular display 24 canresult in a pop-up screen being exhibited, showing machine controlparameters. Alternatively, as illustrated in FIG. 18A, a tap or swipe ona tool representation 18 a′ or 18 b′ on a particular display 24 canresult in a pop-up screen being exhibited, showing further detailedinformation concerning the corresponding tool 18. As described above, incertain embodiments, such finger contacts can be made at the empty areas32 of the display 24. The information correspondingly retrieved isexhibited on at least a part of the display 24, and in certainembodiments, is exhibited in a manner that permits the clamping beamrepresentations 16 a′, 16 b′ and tool representations 18 a′, 18 b′ tostill be shown, at least in part. In certain cases, as a result offurther distinct finger contacts (such as one or more taps or swipeswith one or more fingers) made on the display screen, the retrievedinformation can be expanded/shrunk in size, moved to different locationson the screen, or can be removed in its entirety (either closed down orshifted to be shown on the display tablet 22) so the display 24 canrevert back to exhibiting the clamping beam representations 16 a′, 16 b′and tool representations 18 a′, 18 b′ only.

With reference back to FIG. 12, while the console 36 is shown as beingpositioned on a stand 40 beside the press brake 10, it could just aswell be supported by an extension protruding from the press brake 10.Regardless, the console 36 is generally positioned away from (e.g., offto the side of) the press brake 10 due to the general size of theconsole 36 and lack of area on the press brake 10 for accommodating suchconsole 36. As a consequence of such location of the console 36 withregard to the press brake 10, the operator is able to monitor theworking area 34 for the press brake 10, making sure the area is clearprior to and during deforming operations. However, keeping the console36 away from the press brake 10 also dictates the operator making aplurality of trips between console 36 and press tables 14 or clampingbeams 16 in checking or confirming parameters for the press brakeoperations.

To reduce time spent at the console 36 (such that the deformingoperations can be performed in a timelier manner), the display device 12and/or the display tablet 22 can be configured to provide informationthat the console 36 has conventionally been relied on to convey. Someexamples already described include static information that relates toone or more characteristics concerning the press brake 10, the displaydevice 12, the clamping beams 16, and the forming tools 18 to be used.This information may additionally include check-lists, prompts to verifycertain parameters, instructions/guidance for next process steps, etc.To that end, the more information that the display device 12 and/or thedisplay tablet 24 are configured to provide, the more efficient the timespent at the press brake 10 can be. For example, in certain embodiments,once parameters of the deforming operations are set via the console 36,the display tablet 22 can subsequently be used to convey the informationwhich the console 36 has thereafter been generally relied on to convey.Thus, in certain embodiments, the operator can use the console 36initially for setting the press brake operations, and then spend themajority of time afterward at the press tables 14 for performing theoperations. To that end, it should be understood that there areapplications in which the display tablet 22 may take the place of theconsole 36.

In certain embodiments, the display device 12 is configured to havefunctionality beyond that of a “supplemental” and/or “interfacing”device, as described above. For example, in certain embodiments, thedisplay device 12 can be further configured to function as an“interactive” device with regard to what is shown on its displays 24. Tothat end, the information exhibited (and conveyed to the operator) bythe embodied display device 12 can be static (as exemplified above);however, in the event of certain external cues, the informationexhibited can be changed as necessary. In certain embodiments, theexternal cues can stem from the operator. For example, the external cuescan involve any of a plurality of operator actions. As described above,one such action can involve the operator touching a screen of one of thedisplays 24 via one or more finger contacts, only in such cases, furtherfinger contacts (taps and/or swipes) with the screens of the displays 24can trigger corresponding changes to certain of the informationexhibited on the display.

In certain embodiments, the appearance of change made on the displays 24can be represented in terms of text (e.g., being added, removed, ormodified) and/or color (e.g., being changed from one color to another orsimply being changed to a lighter or darker shade). This would not onlyallow the change to be highly visible, but would serve as a cleardifferentiator from other of the displays 24 that were not changed. Forexample, looking to the exemplary display screen shots of FIGS. 16A and16B, the status of the clamping beams 16 a, 16 b is always shown viacorresponding text. However, because clamp status is crucial toperforming safe deforming operations with the press brake 10, thediffering statuses of the clamping beams 16 a, 16 b (i.e., clamped orunclamped), in certain embodiments, can also be represented via color.An activated (or clamped) status is the safer condition of the two clampstatuses. As such, for an activated (or clamped) status (as provided inFIG. 16A), the representative clamping beams 16 a′, 16 b′ can have acooler color (such as the color blue) along with the written text“CLAMPED” superimposed on the representations 16 a′, 16 b′. Conversely,for a non-activated (or unclamped) status (as provided in FIG. 16B), therepresentative clamping beams 16 a′, 16 b′ can have a very warm (andhighly noticeable) color (such as the color red) along with the writtentext “UNCLAMPED” superimposed on the representations 16 a′, 16 b′.

In certain embodiments, such status pertaining to the clamping beams 16of the tables 14 can be changed via an operator tapping the clampingbeam representations 16 a′, 16 b′ on the display 24. As would beappreciated, upon changing such clamp status on one of the displays 24,the clamps 16 of the corresponding extent of the tables 14 would be soactuated. More of this will be described below. However, at this point,it should be appreciated that other finger contact variations (such asswiping with fingers) could be used just as well. Further, the inventionshould not be limited to operator external cues involving physicalcontact with the screens of the display 24. For example, auditory cuesfrom the operator (captured by speakers 21 positioned on the displaydevice 12) could just as well provide the trigger for such changes,provided the display device 12 and its displays 24 are configured withcorresponding electronics to process (and thereby interpret) theauditory cues and programmed for triggering the desired change to thestatic information. Another example can involve physical cues (i.e.,physical movements, such as gestures of one or more of the operator'shands as positioned on the operator's body) from the operator (capturedby cameras 44 positioned remote from the display device 12 butconfigured for wireless communication with the device 12).

As alluded to above, provided a change is made at the display device 12with regard to characteristics relating to one or more of the pressbrake 10, the display device 12, the tables 14 (or clamps 16 thereon),and the forming tools 18, the actual change to the correspondingapparatus (or portion thereof) may be dictated. In continuing with theexample provided above, if the status of certain of the clamps 16 overan extent of the tables 14 is changed from UNCLAMPED to CLAMPED, thedisplay device 12 must communicate the same to either the console 36,the press brake 10, or a separate clamp control for this to take place.For example, in cases in which the change is only needed to temporarilystop the deforming operations (whereafter the operations are resumed),such communication may only be directed to the press brake 10. However,if the change dictates modification being made to the present orsubsequently-programmed deforming operations, such communication may bedirected to one or more of the press brake 10 and the console 36.

It should be appreciated that such communications can be made possibleby having the display device 12 hardwired to the both the press brake 10and the console 36. However, in certain embodiments, the display device12 is configured for receiving communications from and transmittingcommunications to the console 36 and/or the press brake 10 in a wirelessmanner 38′. Wireless designs are well known in the art, and were alreadybriefly described above with relation to one-way communication to thedisplay device 12. These same teachings would similarly apply here.However, in the case of two-way wireless communication, the displaydevice 12 can be equipped with one or more conventional transceivers andcorresponding electronics to function with Wi-Fi, Bluetooth, or otherwireless protocols. As should be understood, and with reference to FIG.5, changes made with regard to any one of the displays 24 would beinitially processed (e.g., internal to the display device 12) and thenwirelessly transmitted via electronic signals from the display device 12to the console 36 as needed. To that end, the display device 12 can beequipped to receive static information from the console 36 forexhibiting purposes, and any changes made thereto at the displays 24 ofthe device 12 can be in turn transmitted to the console 36 and/or thepress brake 10. In addition, while wireless communication is primarilydiscussed with regard to the display device 12 and the console 36, thedisplay device 12 would be configured to communicate with other poweredaccessories just as well.

As described above, when configured to further function as an“interactive” device, the display device 12 can change the staticinformation being exhibited upon receipt of certain external cues. Suchexternal cues may stem from the operator as described above. However,the invention should not be so limited. Particularly, in cases in whichthe display device 12 is configured for receiving and transmittingsignals, the device 12 may receive signals, with such signalsrepresenting alternate types of external cues.

One example of such signals received by the display device 12 (andrepresenting such external cues) can stem from one or more of theforming tools 18 positioned on the clamping beams 16. FIG. 13 shows aperspective view of an exemplary punch tool 18 a in accordance withcertain embodiments of the invention. In certain embodiments as shown,such tool 18 a has an information tag 42 on an outer surface thereof.While the tag 42 is exemplary shown as a QR code, the tool 18 a couldalternatively have a bar code, RFID tag, or other like toolidentification means which provides a source for information of the tool(e.g., tool ID), with such information being adapted to be queried forassessing such tool information. Tooling that is configured with suchelectronic information storage devices are known to the art and havebeen described, for example, with reference to Applicant's U.S. Pat. No.7,913,533 entitled “Machine Tool Cartridge with Information StorageDevice, Smart Storage Systems, and Methods of Using Smart CartridgeSystems,” the teachings of which are incorporated herein in relevantpart. Given its wireless functionality and transmitting capabilities,the display device 12, in certain embodiments, can query such tools 18a, with corresponding tool information being ascertained by the displaydevice 12. Further, as a consequence of the displays 24 of the device 12being synched, the information of such tools 18 a can be routed to therespective display 24 of the device 12 so as to correspondingly exhibitsuch information.

The tool information that is queried by the display device 12 and routedto the respective display 24 can include any of a plurality ofinformation. For example, as already described, this information caninclude one or more of part number 30 (as perhaps best viewed from FIG.5), part dimensions, and part manufacturer. In certain embodiments,further included in this information is part location. As should beappreciated, using a RFID tag as the tag 42 on the tool 18 a can providespecific information concerning the tool's location. This parameter isparticularly useful in press brake applications, wherein precisepositioning of forming tools 18 on the clamping beams 16 needs to beadhered. To that end, once the tool 18 a is positioned on the upperclamping beam 16 a and queried by the display device 12, if the locationof the tool 18 a on the beam 16 a is interpreted as being incorrect,such can be conveyed to the operator on the corresponding display 24. Incertain embodiments, tool representations 18 a′, 18 b′ (as describedabove with reference to FIG. 5) can be shown as being incorrectlypositioned on the corresponding clamping beam extents by using varying(and clearly discernible) color schemes on the displays 24 and/or byproducing audible signals and/or voice commands in one of a plurality ofdifferent languages, as needed. However, in light of the possible audiocapabilities For example, to indicate incorrect tool positioning of thetools 18, the tool representations 18 a′, 18 b′ can be shown with blackoutline, black background, and white lettering, while tools 18 queriedand determined to be in their correct positions on the table extents areshown with their tool representations 18 a′, 18 b′ shown with blackoutline, white background, and black lettering. However, it should beappreciated that distinguishing the incorrectly-positioned tools 18 canbe exhibited on the displays 24 in any of a wide variety of alternatemanners.

Continuing with the above, in cases of the clamps 16 not being activated(i.e., having unclamped status) or the forming tools 14 not properlylocated on the clamps 16, it has been described that text and/or colorwith regard to the corresponding clamp and tool representations 16 a′,16 b′ and 18 a′, 18 b′ can be used as indicators to the operator. Whileusing both text and color may be considered clear differentiators on thedisplays 24 of the display device 12, if proper attention is not beingpaid to the displays 24, there is potential for the operator to missthese improprieties. To address this, in certain embodiments, when anyimproprieties are discovered by the display device 12 with regard to thedeforming operation, the device 12 can be configured to provide anauditory warning to signal the operator. This functionality dictatesthat the display device 12 be configured with corresponding audioelectronics for triggered via discovery of an impropriety by the device12. The skilled artisan would understand the audio electronics needed,and set-up required, as they are well known in the art. Furthermore, thedisplay device 12, even with its compact size, could accommodate suchelectronics.

Other examples of such signals received by the display device 12 (andrepresenting such external cues) can stem from one or more of miniature2D or 3D cameras. For example, in certain embodiments, such cameras 44can be positioned proximate to or directly on the press brake 10 (toconfirm conditions are met to begin the deforming operations, e.g., tocheck the location of the mounted tools) as exemplarily shown in FIGS.14A and 14B, and/or at one or more locations around the press brake workarea 34 (to confirm no other activity is observed prior to deformingoperations being performed) as exemplarily shown in FIG. 12. Given itswireless functionality and transmitting capabilities, the display device12, in certain embodiments, can receive signals from such cameras 44 tomonitor such environment, and transmit signals to the cameras 44 forredirection thereof as desired.

FIG. 15 shows a flowchart of steps of a method in using the displaydevice 12 (or 12′) in accordance with certain embodiments of theinvention. The method describes steps for the display device 12 during abending operation involving multiple bending sequences, with such stepspossibly being more clearly appreciated with reference to FIGS. 5 and/or17A-17C. To that end, the steps for bending sequences may involvemultiple displays 24 of the display device 12 (such as with displaydevice 12 of FIG. 5) or a single display 24 of the display device 12(such as with display device 12 of FIG. 10). Upon a deforming programbeing sent to the display device 12 via the console 36, step 50 involvesthe corresponding display(s) 24 of the device 12 exhibiting thecorresponding tool setup thereon. This tool set up is provided via thetool representations 18 a′, 18 b′ being shown on the display(s) 24 attheir proper positions on the corresponding exhibited extents of therepresentations of the clamping beams 16 a′, 16 b′. As described above,reference can be made to FIG. 5 (with clamping beam representations 16a′, 16 b′ and forming tool representations 18 a′, 18 b′ shown acrossmultiple displays 24) and FIGS. 17A-17C (with clamping beam and formingtool representations similarly shown on a single display 24). Once thetools 18 (punches 18 a and dies 18 b) have been correspondinglypositioned on the clamping beams 16 by the operator using the display(s)24 as a guide, an optional step 52 can involve confirming thepositioning of the tools 18 given the use of tools 18 having tags 42(such as RFID tags, as described above with reference to FIG. 13 or byutilizing the cameras 44, as described with reference to FIGS. 14A and14B). Such optional step, in certain embodiments, may further includesome “Ready” message being conveyed on the display(s) 24 or displaytablet 22 indicating that the deforming operation can be started.

Step 54 involves a first deforming sequence being queued to begin(exemplarily represented via the display screen shot of FIG. 17A),wherein the display 24 exhibits corresponding tool representations 18 a′18 b′ for the first deforming sequence in highlighted form (with darkercolor shade) with other tool representations 18 a′, 18 b′ exhibited inmuted form (with lighter color shade). In Step 56 (following the end ofthe first deforming sequence), a second deforming sequence is queued tobegin. Such step involves the display 24 showing the first deformingsequence tool representations 18 a′ 18 b′ having been changed to mutedform, and the second deforming sequence tool representations 18 a′ 18 b′having been changed to highlighted form (exemplarily represented via thedisplay screen shot of FIG. 17B). It should be understood that suchseries of muting and highlighting tool representations 18 a′, 18 b′(i.e., steps similar to step 56) will continue until the programmedbending operation is completed. For example, FIG. 17C shows displayscreen shot of display 24 showing an exemplary third and final deformingsequence of the bending operation, wherein tool representations 18 a′,18 b′ for the third deforming sequence have been changed to highlightedform and the tool representations 18 a′, 18 b′ for the second deformingsequence have been changed to muted form. To that end, when the numberof deforming sequences steps have been completed for such bendingoperation, the program will loop back to step 54 until the allotted partrun has been completed, or the operator quits the program.
